Nobody would argue that Agile software development and software architecture don't go hand in hand together, and yet it seems that the software architecture community is much more interested in agile topics than the agile community is in software architecture topics. Is this a case of unrequited love? This presentation explores this question and explores a few possible reasons why this perception of unrequited love between software architecture and agile might exist.

An Agile Practitioner’s Perspective

Hypothesis…

The National Agile conference will have
fewer talks about software architecture
than SATURN has talks about Agile.
Implication: Architecture’s “love” for
agile is not returned.
How many speaker sessions might
work at either Agile or SATURN?
• Reviewed session keywords, titles,
abstracts, common speakers
– National Agile conference and SATURN
• Used some “expert judgment”
– Regular speaker and attendee
– Technical committee member for Agile and
SATURN since 2012 and 2013 respectively
– Master in Software Engineering5

Percentage of total sessions…
How many speaker sessions might
work at either Agile or SATURN?
By the numbers… Since 2011
• 5% of talks at Agile were likely relevant to
SATURN audience
– Approx 30 of 580
• 22% of talks at SATURN were likely
directly relevant to Agile audience
– Approximately 35 / 160
• Interesting aside: European Agile
conferences have greater focus on
architecture and design than in US8
SATURN “Best Presentation”
Awards presented by IEEE, SEI
• “Architecture in Practice” Best Presentation award started in 2010
– “Awarded to the presentation that best describes experiences, methods, and lessons learned from the implementation of architecture-centric practices.”
• Award decided by attendees
– Voting cards
• 4 out of 5 awards given to agile or lean topics since 2010

From whence doth this apparent
unrequited love arise?

I had a great idea over the weekend
that we just have to get in the next

There's a trend emerging we didn't anticipate and I need this feature in the next release so we can

Software systems are built on
easily changeable premises.
This is a good thing.

Hi, Agile, I'm ready to embrace
change!
*sigh* it's that software architecture again... he's just so...
structured..
26
Agile promotes preserving choice.
Software architecture promotes preserving structure.
Natural tension between Agile and architecture…
27
Lots of things have to work “just right” for a team to be agile.
We think software architecture is one of the more important and
interesting areas.

SATURN is an amazing conference
for Agile Architects!
SATURN is for Agile Architects
• Smaller conference
– Greater engagement
– More meaningful networking
• Lower costs
– Better value – lower $$ / relevant knowledge
• Narrower focus
– Greater number of relevant sessions
– Higher density of usable software architecture
